Application filed September 4, 1915. Serial No. 49,026.

To all whom it may concern;

Be it known that 1, MICHAEL KANTRO, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Envelops, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to envelops and has for its objectthe production of a simple and efficient envelop formed from a blank sheet of paper or other suitable material which when folded will produce an envelop or file comprising a plurality of pockets.

Another object of this invention is the production of a simple and efiicient envelop wherein the same may be quickly and efficiently folded for the purpose of dividing the envelop into a plurality of compartments.

A still further object of this invention is the production of a simple and eiiicient envelop which may not only be used as a mailing receptacle but may also be usedas a file for the purpose of preserving records and the like.

With these and other objects in view, this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is afront elevation of an envelop constructed in accordance with the present invention, showing the envelop in a finished or folded position.

Fig. 2 is a top plan view of the structure shown in Fig. 1.

F ig. 3 is a front elevation of an envelop showing a slightly modified form of the invention, wherein two distinct and difierent sized pockets are employed.

Fig. 8 is a top plan view of the structure shown in Fig. 7 showing the envelop or file provided with six pockets.

Fig. 9 is a front elevation of still another embodimentof the invention, showing the envelop having the pockets formed therein and showing the body provided with wire lacings or stitchings in place of being glued or otherwise secured together.

Flg. 9 1s a top plan view of the structure shown in Fig. 9.

Fig. 10 is a front elevation of still another embodiment of the invention.

Fig. 11 1s a top plan view of the structure shown in Fig. 10.

Fig. 12 is a plan view of the blank from which the envelop is formed.

Fig. 13 is a top plan view of still another embodiment of the invention.

Fig. 14 is a front elevation of the structure shown in Fig. 13, showing the manner in which the ends of the pockets are locked together or anchored.

Fig. 15 is a front elevation of still another form of securing or anchoring the ends of the wings of the envelop to constitute the pockets.

Fig. 16 is a top plan view of an envelop having the ends of the wings anchored as illustrated in Fig. 15.

Fig. 17 is a section taken on line 17-17 of Fig. 14:.

Fig. 18 is a section taken on line 18-18 of Fig. 15.

Fig. 19 is a detailed perspective of one of the interlocking tongues which may be employed for locking the wings of the envelop together.

Fig. 20 is a front elevation of a portion of the envelop showing one of the modified forms as provided with a difierent form of interlocking tongue such as is illustrated in Fig. 19.

Fig. 21 is a diagrammatic view in top plan of a modified form of the envelop, showing a double envelop such as is illustrated in Fig. 5, Fig. 5 showing the single construction of the envelop.

Fig. 22 is a plan view of the sheet or blank from which the structure shown in Fig. 21 is formed.

Referring to the accompanying drawings by numerals it will be seen that 1 designates the body of the envelop which is provided with an outer flap 2, the outer flap 2 being also provided with a pair of side flaps 3.

The body 1 is provided with end wings 4, which end wings 4 are in turn provided with securing flaps 5 at the outer edges thereof.

It of course should be understood that the body 1 aswell as the wings a may be provided with the usual notched or cut-out portions 6 as illustrated clearly in Fig. 6 of the drawings for the purpose of permitting articles placed within the respective pockets of the envelop to be readily removed.

When the envelop is folded, the outer flap 2 is folded against the body 1, the wings f first having been folded upon the body 1 so as to extend between the outer flap 2 and the body 1, which structure is clearly illustrated in top plan view in Fig. 2 of the drawings.

Upon carefully considering Fig. 2, it Wlll be seen that the side flaps 3 of the front flap 2 are bent so as to overlap the edges of the body 1 and are secured thereto by means of paste or other suitable adhesive material, although of course it should be understood that any means desired may be employed for attaching the flaps 3 to the bottom 1.

The end flaps '5 of the wings l are folded backwardly upon the wings 4 as illustrated in Fig. 2 of the drawings and the inner faces of the end flaps 5 are securely fastened by means of adhesive material to the inner face of the front flap 2, thereby producing a pair of pockets 7 adjacent the front flap 2 and an elongated pocket 8 in front of the pocket 7, adjacent the body portion 1 of the envelop.

It of course should be understood that any suitable flap 9 may be employed for the purpose of closing or sealing the top of the envelop without departing from the spirit of the invention. This flap 9 may or may not be used in connection with the envelop, according to the desire of the user of the envelop. It is especially desirous to eliminate this sealing flap 9 when the envelop is used as a file.

Now referring particularly to Figs. 4 and 5 of the drawings, it will be seen that a slightly modified form of the invention is illustrated wherein the front portion 2 of the envelop in the structure shown in Figs. 3 and 4: has the side flaps 3 thereof bent so as to overlap the front body portion 1 of the envelop. The wings 4 of the envelop have their flap portions 5 folded backwardly so as to have these flap portions 5 engage the end face of the body portion 1 of tie envelop and produce a pair of adjoining pockets 7 upon the portion of the envelop adjacent the body 1 and an elongated pocket 8 adjacent the front flap 2.

In Fig. 3 there is shown still another embodiment of the invention wherein the front body portion 1 flap 2" is employed, having the end flaps'3 folded over so as to overlap the edges of the The body portion 1 is provided with a winged portion 45* which extends across the entire length of the envelop. The opposite side edge of the body portion 1 is also provided with a wing portion 4 having a flap 5, the flap 5 being secured by means of adhesive material or other suitable fastening means to the inner face 10 of the wing P. By means of the structure illustrated in Fig. 5, it will be seen that a pair of pockets 11 and 12 are produced extending the entire length of the envelop and an intermediate short pocket 13 is also formed by means of the wing portion 49. This structure is clearly illustrated in Fig. 5 of the drawings.

It should be understood that Figs. 4 and 3 are substantially the same structure as that shown in Fig. 1 with the exception of the method of securing the wings 4. to the body 1, one of the pockets 7 being slightly less in width than the other pocket 7.

By carefully considering Figs. 7 and 8 it will be seen that 1a designates the front flap, which front flap is provided with a wing 15 and a wing 16. The wings 15 and 16 are overlapped or in other words have their respective ends overlapping and the flap 17 of the wing 16 is secured to the inner face of the front flap 14 whereas the flap 18'of the wing 15 is secured to the inner face of the flap 16 for producing pockets 19 and '20.

The body portion 21 of the envelop is provided with wings 2 2 and 23 which overlap having the flap portion 24 of the wing 23 engaging one face of the wing 22, whereas the flap portion 25 of the wing 22 engages the inner face of the body 21 for producing apocket 26 and a pocket 27 7 By carefully considering Figs. 7 and 8 it will be further seen that the front flap 14; will constitute one section and the body portion 21 will constitute a second section,"the respective edges of the sections being secured together by means of an end binding strip 23, thereby producing a long or large pocket 29 between the several sections of the 1 envelop.

By considering Figs. 9 and 9 it will be seen that a plurality of short pockets 30 and 31 may be provided by means of passing the wire lacing or stitch 32 through the envelop as illustrated in Figs. 9 and 9 when so desired without employing the flaps as previously described. 7

In Figs. 10 and 11 there is shown an embodiment of the invention wherein the envelop is illustrated as comprising a primary section 33 and an auxiliary section 34 for producing a' plurality of pockets as illustrated, the respective ends being secured together by means of binding strips 35. V

In Figs. 13 and 17 it will beseen that the envelop is shown as being provided with a body 36 and a front flap 37, thewings 38 of the body 36 being provided with a plurality of projecting tongues 39 passing through the slots 40 formed in the body 36 and being bent oppositely and folded backwardly and secured by means of adhesive material or in any other suitable or convenient manner.

As illustrated in Figs. 15 and 16, a front flap 4:1 is provided to which is secured the body 42 having Wings 43 and 44, the wings 4C3 and 44 being provided with tongues 4L5 which are adapted to pass through apertures 4.6 and engage the outer faces of the body 4L2 and wing 44 as illustrated in Fig. 16.

In Figs. 19 and 20 there is shown an embodiment of the locking tongue structure such as is described with respect to Figs. 13, 14, 15 and 16, wherein the tongue 47 is provided with a depending lip 48 adapted to pass through the aperture -19 in an adjacent section as illustrated in Fig. 20 to lock the several sections together. This structure shown in Figs. 19 and 20 may be employed independent or in a similar manner as that illustrated in Figs. 13 to 16 inclusive.

It should be understood that any number of pockets may be produced by placing an insert within the envelop. It should be fur ther understood that the device may be made of any size or any material without departing from the spirit of the invention.

What I claim is 1. As a new article of manufacture, an envelop formed from a single piece of material comprising an outer flap, a body, side flaps secured to said outer flap, end Wings carried by said body, securing flaps carried by the ends of said end wings, said securing flaps being bent backwardly upon said end wings and being secured to the inner face of the outer flap for producing a plurality of pockets, and said side flaps being folded around the side edges of said body and being secured to the outer face of said body for firmly holding the ends of said body in engagement with said outer flap.

2. As a new article of manufacture, an envelop formed from a single piece of material comprising an outer flap, a body, end wings secured to said body, securing flaps carried by the ends of said end wings, said securing flaps being bent backwardly upon said end wings, the outer faces of said securing flaps being secured to the adjoining faces of the adjoining end wings for producing a plurality of pockets.

In testimony whereof I hereunto afiix my signature.
